a teacher asked me where are all these video? Should i say go opal2.0 to find? I don't think they still exist

Copyright concerns have played a significant role in limiting the spread of educational resources. Copyright law grants authors and creators exclusive rights to their works, such as the right to reproduce, distribute, and publicly display their works. This means that unless an educational resource is in the public domain or licensed under a permissive open license, such as Creative Commons, it may be subject to copyright infringement if it is shared without permission. So for 11 years, I didn't share these video made in collaboration with NUS, Prof Sow. Technically, the copyright owner is MOE but i speculate the videos are lost already from e-Media, to edumall, to ishare, to opal2.0.... 

This can create significant barriers to the sharing and dissemination of educational resources, particularly for teachers and educators who may want to share resources with their students or colleagues. For example, if a teacher creates a lesson plan or a set of materials for their class, they may be unable to share those resources freely with other teachers or educators without running afoul of copyright law.

Furthermore, copyright concerns can also limit the ability of students to access and use educational resources. For example, if a textbook is subject to strict copyright restrictions, students may be unable to make copies or share the textbook with their classmates, making it more difficult for them to study and learn.

In addition to these practical concerns, copyright concerns can also create a culture of fear and uncertainty around the sharing of educational resources. Teachers and educators may be hesitant to share resources for fear of being accused of copyright infringement, even if their use of the resources would likely be considered fair use under the law. I hope since the copy in edumall ( now called opal2.0 but the copy of these video are not in opal2.0 i think, some how lost after many system rise and fall)

Overall, copyright concerns can make the spread of educational resources difficult, limiting access to information and hindering the ability of teachers and educators to share knowledge and collaborate with one another.

Let me know, if I should share these video and just tell me teachers friends that they not longer exist in MOE sharable resources.
